BACKGROUND 1. Technical Field

The present disclosure relates to the field of software development. More particularly, the present disclosure relates to a method for generating an application programming interface for facilitating software development and testing.

2. Background

When a software developer begins a process of generating new software for an application, there is a need to create an application programming interface (API) that enables a user to develop the software efficiently and connect with other systems.

Typically, the process of creating and deploying an API requires that the software developer set up a particular environment, create the API, and then manage the deployment process in a manner that satisfies organizational standards and also addresses potential security vulnerabilities. In addition, this process is generally a manual process that is performed separately for each individual software development project. For these reasons, the process may be time-consuming and cumbersome.

Accordingly, there is a need for a simplified methodology for creating an API that facilitates software development.

FIG. 2 is a block diagram of a networked system 200 that includes a client computer 210 that is communicatively connected to at least one server computer 220 via a network 230, according to an exemplary embodiment. Referring to FIG. 2, each of client computer 210 and server computer 220 may be equivalent to computer system 100 as illustrated in FIG. 1. Network 230 may include any type of network that implements a communicative connection between client computer 210 and server computer 220, such as, for example, a local area network (LAN), a wide area network (WAN), or the Internet.

The client computer 210 may include a software module 240 that includes instructions that are executable by the client computer 210 to perform a method for generating an API, in accordance with an exemplary embodiment. Referring also to FIG. 1, the software module 240 may be provided in conjunction with processor 110. Alternatively, the software module 240 may be stored in any one or more of main memory 120, static memory 130, or computer readable medium 182.

FIG. 3 is a flowchart 300 that illustrates a method for generating an API, according to an exemplary embodiment. The method may be implemented, for example, as a set of instructions that are executable by a computer to generate an API.

In operation 310, a first user input is received via a user interface. The first user input may include, for example, column names, filters, and/or groupings that specify at least one requirement that relates to the API being created. These requirements are then translated into a query, such as, for example, a Structured Query Language (SQL) query or a MapReduce query. The user interface may provide a drop-down menu that includes several menu items from which a user may indicate selections that then serve as the first user input. The user interface may be displayed, for example, on any one or more of client computer 210 and/or other computers that are communicatively coupled to client computer 210 via network 230. With respect to the query, a user may have an option to specify query statements, which may be analyzed to detect issues that may potentially impact the performance of the API being created.

In operation 320, a first template for the API is provided. The first template may be obtained from among a plurality of predetermined templates that are generated in advance and stored in a database that is accessible by server computer 220 and/or available via an application such as, for example, API Generator. Alternatively, the first template may be “built from scratch”, i.e., a user may create a template to be used as the first template for the API.

In operation 330, the first template is uploaded to a software development tracker. The term “software development tracker” refers to a continuous software integration module for tracking software changes, testing, and reporting updates and new versions, such as, for example, Git/Bitbucket.

In operation 340, automated tests are generated and a user may review the API in testing and development environments. In addition, users may make changes to the API and re-deploy the revised version of the API to the testing and development environments. In an exemplary embodiment, this process is fully automated with Jenkins/Jules and Git/Bitbucket. When no further changes are needed and an approval is obtained, the API is then ready for deployment to a production environment.

In an exemplary embodiment, a user may have an option to specify his own SQL for an API. The testing and development environment may include a capability to find potential improvements in the specified SQL in order to increase a performance quality of an API. Previously released APIs may also be scanned to detect performance issues that may have been caused by suboptimal queries. In an exemplary embodiment, artificial intelligence (AI) techniques and/or machine learning techniques may be used to identify these potential improvements.

In an exemplary embodiment, the testing and development environment may include a determination of one or more data structures to be used in the generation of the API. This determination may be implemented by matching at least one of the query and columnar data with at least one potential data source. Further, a machine learning algorithm may be used to generate metadata that relates to the determined data structures, and the generated metadata may then be used to update one or more of the templates to be used for generating new APIs.

The determination of the data structures may result from an application of data principles, such as, for example, Payment Card Industry (PCI) data security standards, that identify proper and/or authoritative data sources. In an exemplary embodiment, the determination of the data structures may further entail implementing a cross-reference rules check to find proximity of appropriate data principles and applicability to received user information.

In an exemplary embodiment, the testing and development environment may further include an implementation of a caching rule that relates to hosting data locally and ensuring good query times with respect to scheduling, triggering, direct invocation, and indirect invocation. The caching rule may include checking received queries to ensure that query times, query bandwidths, and query record counts are optimally balanced.

In an exemplary embodiment, the testing and development environment may further include a setting of an access control list in response to a received user system request that enables one or more security protocols. The access control list may be calculated based on a set of connectors that results from the security protocols.

In operation 350, the API is deployed to the production environment and made available to a general user population.

FIG. 4 shows a data flow diagram that illustrates an information flow that is concurrent with a process for creating and managing an API, according to an exemplary embodiment. In particular, at the left side of FIG. 4, a request is received, and the request is routed to an API Creator+Management Console, and from there the request is forwarded to an API Template repository. A template is selected from among a pre-generated set of templates by the API Template repository, and the selected template is then routed to the API Creator, which may generate code based on the template. Code is then published to Bitbucket and Jenkins/Jules for deployment. The template and any additional feedback input generated by Jules are then forwarded to three different destinations: a developer node, a user acceptance testing (UAT) node, and a production node. Each of these nodes has access to an SQL database, and may also provide additional input. The result is then forwarded back to the API Creator+Management Console, which is configured to generate an API based on these inputs. In the event that further user input is provided at the initial request node, that input may be processed such that the API is subsequently updated based on the result of the further processing.

In an exemplary embodiment, as more users utilize the methodologies illustrated in FIGS. 3 and 4, a priority of options may be generated based on user feedback, organizational relationships, and whether prior situational recommendations have been successful. In this aspect, data inputs and outputs may be clustered, and the clustered data may be used to provide feedback results in order to improve future generations of APIs.

While the computer-readable medium is shown to be a single medium, the term “computer-readable medium” includes a single medium or multiple media, such as a centralized or distributed database, and/or associated caches and servers that store one or more sets of instructions. The term “computer-readable medium” shall also include any medium that is capable of storing, encoding or carrying a set of instructions for execution by a processor or that cause a computer system to perform any one or more of the methods or operations disclosed herein.

In a particular non-limiting, exemplary embodiment, the computer-readable medium can include a solid-state memory such as a memory card or other package that houses one or more non-volatile read-only memories. Further, the computer-readable medium can be a random access memory or other volatile re-writable memory. Additionally, the computer-readable medium can include a magneto-optical or optical medium, such as a disk or tapes or other storage device to capture carrier wave signals such as a signal communicated over a transmission medium. Accordingly, the disclosure is considered to include any computer-readable medium or other equivalents and successor media, in which data or instructions may be stored.

Although the present specification describes components and functions that may be implemented in particular embodiments with reference to particular standards and protocols, the disclosure is not limited to such standards and protocols.
